Hi, my name is Huaizhi Yang, but just call me Ketro for short. I am going to my year 2 of my IB journey. I am from Fuzhou, China, but I'm currently studying in Michael Power St. Joseph High School in Toronto, Canada. I love astronomy, aviation, and monstercat. We have learned Micropipeting and Gel Electrophoresis in the first part of IB biology.
